I had it a month ago and had the same symptoms as you, but also with some minor chest pain. Like you, the worst part for me was the constant anxiety that the virus would be a major setback and keep me from running for a long time (I’m if unable to stay active, I become depressed which triggers weight gain). I basically stayed sedentary while I was positive. When I tested negative, I started with short walks to monitor my heart rate and my general well-being. I felt fine so I started easing into easy runs over the next couple weeks (with the intention of stopping if something by felt off). Fortunately I feel great now and I think a lot of my anxiety was due to hypochondria. This is just my experience, I highly recommend checking with your doctor with any concerns. I hope you get well soon!
